Snap Action, Limit Switches - 1LS9-L Application Field and Working Principle

Snap action, limit switches are electromechanical devices for switching on or off transmission of electricity by physical movement. The 1LS9-L limit switch is designed to be used in industrial automation to control movement or switching on a machine process. It functions through the mechanism of a two-stage lever arm that is actuated by cam movement and opens or closes the connection.

Field of use

The 1LS9-L limit switch can be used in a variety of industrial applications where accurate control of a machine process is needed. This switch is used when a lever is to be actuated as a result of a position or angle regulation, or to limit maximum or minimum displacement. It is also used to detect and respond to the displacement of a moving mechanical part or machine operation. Common applications for the 1LS9-L limit switch include industrial machinery control, motion control systems, safety guards, robots and automated machines.

Construction

The 1LS9-L limit switch is housed in a stainless steel case and features a two-stage lever arm actuated by cam movement. It includes a brightly colored lever arm to indicate the open or closed state. The main switch comprises two surface contact rated to 80A at 250V and one snap-action contact rated to 0.5A at 250V. The contacts are designed to open-short or close-make when the lever is actuated. The case is designed to meet the IP67 degree of protection.

Operation principle

The 1LS9-L limit switch operates according to the basic principle of the lever arm actuated by cam movement. When the lever arm is actuated, its two-stage cam system drives the actuating arm to open or close the contact, depending on the position of the cam. The contact is designed to open-short or close-make when the lever arm is actuated, and is rated for a maximum current of 80A at 250V.

Installation and maintenance

The 1LS9-L limit switch is designed for easy installation and maintenance. All components can be quickly removed from the case for easy access. The contacts are easy to open or close as needed and can be accessed quickly for cleaning or replacement. The switch can be mounted directly on a motor or any other machine component. The limit switch is CE certified and comes with all necessary mounting hardware.

Conclusion

The 1LS9-L limit switch is a reliable and accurate solution for industrial automation and machine process control. It is engineered with a two-stage lever arm actuated by cam movement and is designed to open or close the contact when the lever is actuated. With easy installation and maintenance, the switch is a cost-effective solution for industrial automation and process control.
